Abstract
Abstract An apparatus mountable atop a container having a cavity containing a solid material, an orifice positioned atop the container and a liquid inlet. The apparatus has a collar having an axial bore, a pivotable conduit attached to the collar and a diffuser attached to the conduit. The apparatus ensures that solid material within the container remains flooded during dispensing of liquid from the container and provides convenient accessibility to the diffuser for removal, inspection and replacement. The apparatus is particularly well suited for dispensing of liquids containing solid halogen donor materials from solid halogen donor containers.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
158 words
A liquid dispensing apparatus for dispensing liquid from a container, said apparatus comprising: a) a container attachment means having a bore; b) a pivotable liquid outlet means removably attached to said container attachment means, said pivotable liquid outlet means having a first and a second bore, a liquid outlet port in fluid communication with said second bore and a pressure relief port in fluid communication with said first bore, said first bore in fluid communication with said bore of said container attachment means; and c) a diffuser means removably attached to said pivotable liquid outlet means and disposed within said bore of said container attachment means and within said first and said second bores of said pivotable liquid outlet means, said diffuser means providing fluid communication from said first bore to said second bore of said pivotable liquid outlet means; wherein said diffuser means is removable from said pivotable outlet means to facilitate diffuser means inspection and replacement.
Claim 2
Dependent Claim
158 words
A liquid dispensing apparatus for dispensing liquid from a container, said apparatus comprising: a) a container attachment means having a bore; b) a pivotable liquid outlet means removably attached to said container attachment means, said pivotable liquid outlet means having a first and a second bore, a liquid outlet port in fluid communication with said second bore and a pressure relief port in fluid communication with said first bore, said first bore in fluid communication with said bore of said container attachment means; and c) a diffuser means removably attached to said pivotable liquid outlet means and disposed within said bore of said container attachment means and within said first and said second bores of said pivotable liquid outlet means, said diffuser means providing fluid communication from said first bore to said second bore of said pivotable liquid outlet means; wherein said diffuser means is removable from said pivotable outlet means to facilitate diffuser means inspection and replacement.
Claim 3
Dependent Claim
34 words
The apparatus of claim 1 wherein said pivotable liquid outlet means is pivotable 360° about said first and second bores of said pivotable liquid outlet means and said bore of said container attachment means.
Claim 4
Dependent Claim
23 words
The apparatus of claim 2 wherein said liquid outlet port of said pivotable liquid outlet means is removably connected to a vacuum breaker.
Claim 5
Dependent Claim
24 words
The apparatus of claim 3 wherein said pressure relief port of said pivotable liquid outlet means is removably connected to a pressure relief valve.
Claim 6
Dependent Claim
22 words
The apparatus of claim 2 wherein said pivotable liquid outlet means is secured to said container attachment means by a ring clamp.
Claim 7
Dependent Claim
295 words
A liquid dispensing apparatus for dispensing liquid from a container containing a liquid and a solid halogen donor material, said apparatus comprising: a) a container attachment means having a bore; b) a pivotable liquid outlet means, removably attached to said container attachment means, said pivotable liquid outlet means having a first and a second bore, a liquid outlet port in fluid communication with said second bore and a pressure relief port in fluid communication with said first bore, said first bore in fluid communication with said bore of said container attachment means, said liquid outlet port removably connected to a vacuum breaker, said pressure relief port removably connected to a pressure relief value, said pivotable liquid outlet means secured to said container attachment means by a ring clamp wherein said pivotable liquid outlet means is pivotable about said first and second bores of said outlet means and said central bore of said container attachment means; and c) a diffuser means removably attached to said pivotable liquid outlet means and disposed within said bore of said container attachment means and within said first and said second bores of said pivotable liquid outlet means, said diffuser means providing fluid communication from said first bore to said second bore of said pivotable liquid outlet means; wherein liquid flowing into the container from a liquid inlet completely floods the solid halogen donor material and dissolves a portion of the solid halogen donor material, flows through and is filtered by said diffuser means, flows from said diffuser means into said second bore of said pivotable liquid outlet means, and is dispensed from said second bore through said liquid outlet port, and wherein said diffuser means is removable from said pivotable outlet means to facilitate said diffuser means inspection and replacement.
Claim 8
Dependent Claim
295 words
A liquid dispensing apparatus for dispensing liquid from a container containing a liquid and a solid halogen donor material, said apparatus comprising: a) a container attachment means having a bore; b) a pivotable liquid outlet means, removably attached to said container attachment means, said pivotable liquid outlet means having a first and a second bore, a liquid outlet port in fluid communication with said second bore and a pressure relief port in fluid communication with said first bore, said first bore in fluid communication with said bore of said container attachment means, said liquid outlet port removably connected to a vacuum breaker, said pressure relief port removably connected to a pressure relief value, said pivotable liquid outlet means secured to said container attachment means by a ring clamp wherein said pivotable liquid outlet means is pivotable about said first and second bores of said outlet means and said central bore of said container attachment means; and c) a diffuser means removably attached to said pivotable liquid outlet means and disposed within said bore of said container attachment means and within said first and said second bores of said pivotable liquid outlet means, said diffuser means providing fluid communication from said first bore to said second bore of said pivotable liquid outlet means; wherein liquid flowing into the container from a liquid inlet completely floods the solid halogen donor material and dissolves a portion of the solid halogen donor material, flows through and is filtered by said diffuser means, flows from said diffuser means into said second bore of said pivotable liquid outlet means, and is dispensed from said second bore through said liquid outlet port, and wherein said diffuser means is removable from said pivotable outlet means to facilitate said diffuser means inspection and replacement.
